Specifically, the left end of the spring 104 is fixedly connected to the fixed block 102, and the right end of the spring 104 is fixedly connected to the push block 103. The upper surface of the push block 103 abuts against the bottom of the sieve plate 10. The push block 103 is placed on the mounting plate 101 and is slidably matched with the mounting plate 101. A first motor 105 is fixedly installed on the frame 1. The first motor 105 is drivingly connected to a first rotating shaft 106. The first rotating shaft 106 is rotatably arranged on the frame 1. A cam 107 is fixedly installed on the first rotating shaft 106. The cam 107 abuts against the push block 103.
[0024] Preferably, sliders are fixed on both sides of the push block 103. The sliders are slidably matched with guide rails, and the guide rails are fixed on the frame 1.
[0025] As a further explanation of this embodiment, a second rotating shaft 201 is coaxially fixed inside the drum sieve 20. Specifically, one ends of a plurality of rotating rods are fixedly installed on the second rotating shaft 201 along its length direction, and the other ends of the rotating rods are fixed to the inner wall of the drum sieve 20. A thread ring 202 is fixedly arranged on the inner side wall of the drum sieve 20 along its length direction. A second motor 203 is installed on the frame 1. The second motor 203 is drivingly connected to the second rotating shaft 201.
[0026] As a further explanation of this embodiment, a first driving pulley 110 is fixedly connected to the output shaft of the first motor 105. A first driven pulley 111 is fixedly installed at one end of the first rotating shaft 106 close to the first motor 105. The first driving pulley 110 and the first driven pulley 111 are drivingly connected by a first belt 112.
[0027] As a further explanation of this embodiment, a second driving pulley 210 is fixedly connected to the output shaft of the second motor 203. A second driven pulley 211 is fixedly installed at one end of the second rotating shaft 201 close to the second motor 203. The second driving pulley 210 and the second driven pulley 211 are drivingly connected by a second belt 212.
[0028] As a further explanation of this embodiment, first baffles 30 extending upward are fixedly installed on the front and rear sides of the receiving plate 13.

[0030] The working principle of this device is as follows: The pellets to be screened are put into the first feed hopper 11. Start the first motor 105 and the second motor 203. The rotation of the first motor 105 drives the rotation of the first driving pulley 110, which drives the rotation of the first driven pulley 111 through the first belt 112, thereby driving the rotation of the first rotating shaft 106 and the cam 107. The outer wall of the cam 107 continuously abuts against the push block 103. When the small-diameter part of the cam 107 abuts against the push block 103, it drives the push block 103 to move forward, so that one end of the sieve plate 10 rises. When the large-diameter part of the cam 107 abuts against the push block 103, the push block 103 moves backward under the action of the spring 104, so that one end of the sieve plate 10 descends. In this way, one end of the sieve plate 10 continuously rises and falls, shaking the pellets on the sieve plate 10. The pellets can fall onto the receiving plate 13 through the mesh holes on the sieve plate 10, and the large impurities fall into the aggregate hopper 12 along the sieve plate 10.
[0031] The rotation of the second motor 203 drives the rotation of the second driving pulley 210, which drives the rotation of the second driven pulley 211, and further drives the rotation of the second rotating shaft 201. The second rotating shaft 201 drives the rotary screen 20 to rotate.
[0032] The pellets move along the receiving plate 13 to the second feed hopper 22 and then fall into the rotary screen 20. They are pushed downstream of the rotary screen 20 through the thread rings 202 in the rotary screen 20. The broken pellets and small impurities fall into the dust guide hopper 40 through the sieve holes on the rotary screen 20, and the normal pellets are discharged through the second discharge port 21.
[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
